Ammonia synthesis reactions, enabled by the Haber-Bosch process, account for approximately 3% of the world’s total energy use. Here, we propose a cascade reactor with a sequence of catalyst compositions which are tailored to a specific stage of the synthesis reaction. The various catalyst compositions are enabled by our novel, direct joule heating process for synthesizing high entropy alloy nano ...

Sensor networks embedded on structures, such as pipes, bridges, railways, aircraft wings and fuselage, among others, are required to transfer data related to the health of the structure. This data is typically sent to a central location where it can be processed, displayed, and analyzed. Typical Structural Health Monitoring (SHM) uses embedded ultrasonic transducers exclusively for non-destructive ...

Graded rare earth hafnia multilayer coatings with three different top layer compositions will be deposited on SiC CMC and alumina substrates, characterized by XRD, SEM and EDS, and subjectedtoflowing air-steam at 50% relative humidity without and with CMAS in both isothermal and thermal cycling conditions.Post test analyses include weight change, SEM microstructure characterization changes, XRD/ED ...

Conventional vehicle armor has evolved considerably over the years, including homogeneous plates, composite materials, and reactive substrates.Variable orientations have also been implemented, including curved, sloped, angled, and spaced plates.A common characteristic among these conventional armor solutions is that they are static and incapable of changing in response to local threats.Adding a me ...

To obtain spectrum dominance the U.S. Navy needs to make use of all the Radio Frequency assets on their SWAP-constrained platforms. Thus it is critical that the apertures available can be used as effective active and passive radar, high-data-rate communications, ELINT/SIGINT, ESM and Electronic Protection (EP) and Electronic Warfare (EW) systems. Integrating these capabilities into a single multi- ...

Development of an efficient device capable of concentrating ultrafine radioactive particulate aerosols is essential to the detection of nuclear detonations using a Radionuclide Aerosol Sampler and Analyzer (RASA) system as well as U.S. Navys development of a fast acting naval radiation detection system. We propose to develop an efficient device for ultrafine particulate aerosol concentration and s ...

TASK IMILITARY UNIT SICKWEATHER APP In this task, the Sickweather app will be modified to host units with commanders and medical personnel with admin rights. Those with admin rights will be able to add and remove military personnel from their assigned units and collect data on the health of their unit, units around them and the civilian population.TASK IIDATA INTEGRATION In this task, SickScores, ...

Inspection of Landing Gear (LG) components is an essential part of standard maintenance procedures to ensure the long-term health of aircrafts. Existing non-destructive inspection (NDI) techniques, such as fluorescent penetrant inspection, magnetic particles, eddy current, ultrasound etc., often require the removal of coatings and or are not efficient. We propose to develop and test a novel NDI sy ...
